[0019] Electronic products generally have waterproof requirements. While meeting the waterproof function, the product must also be able to breathe with the external environment. In the existing technology, the general solution is to attach a waterproof and breathable membrane to the outer surface of the product and then cover the waterproof and breathable membrane with a decorative cover. This technical solution adds the decorative cover component, thereby increasing costs and affecting production efficiency.
[0020] To address the aforementioned problems, this utility model proposes a waterproof and breathable structure and electronic product, aiming to provide a cost-effective and production-efficient waterproof and breathable structure and electronic product. Figures 1 to 4 This is a schematic diagram of one embodiment of the waterproof and breathable structure provided by this utility model.
[0021] Please refer to Figures 1 to 3 In one embodiment of this utility model, the waterproof and breathable structure 100 includes a shell 1 and a waterproof and breathable membrane 2. The shell 1 has a breathable channel 11 formed inside it. One end of the breathable channel 11 penetrates the outer surface of the shell 1 to form an external breathable hole 111, and the other end communicates with the inner cavity of the shell 1 to form an internal breathable hole 112 inside the shell 1. The waterproof and breathable membrane 2 is disposed inside the shell 1. The waterproof and breathable membrane 2 is located on the breathable channel 11 or is disposed corresponding to the internal breathable hole 112 to allow air flowing through the breathable channel 11 to pass through and to isolate water entering from the external breathable hole 111.
[0022] In this technical solution, the housing 1 has an internal ventilation channel 11. One end of the ventilation channel 11 penetrates the outer surface of the housing 1 to form an external ventilation hole 111, and the other end connects to the inner cavity of the housing 1 to form an internal ventilation hole 112. The waterproof and breathable membrane 2 is positioned on the ventilation channel 11 or corresponding to the internal ventilation hole 112, thereby allowing air to flow through the ventilation channel 11 and isolating water entering through the external ventilation hole 111. This achieves that the waterproof and breathable structure 100 is both waterproof and breathable.
[0023] This design eliminates the need for additional components, thus saving on the cost of such components and improving production efficiency. Furthermore, the ventilation channel 11 in the housing 1 and the waterproof and breathable membrane 2 further enhance the breathability of the finished product while preventing external water from entering the electronic product 200, thereby ensuring the reliability and safety of the electronic product 200.
[0024] Further, please refer to Figure 2 and Figure 3 An installation groove 131 is formed within the housing 1, and the bottom wall of the installation groove 131 communicates with the internal vent hole 112. The waterproof and breathable membrane 2 is attached to the installation groove 131. It is understood that the waterproof and breathable membrane 2 is relatively smooth. In some embodiments, the waterproof and breathable membrane 2 can directly cover the internal vent hole 112 and be directly attached to the inside of the housing 1. However, due to the smooth nature of the waterproof and breathable membrane 2, it is prone to displacement during use, thus rendering the finished product waterproof and causing safety hazards. Therefore, in other embodiments, the installation groove 131 is formed within the housing 1, and the bottom wall of the installation groove 131 communicates with the internal vent hole 112. The waterproof and breathable membrane 2 is attached to the installation groove 131. With this arrangement, the waterproof and breathable membrane 2 is prevented from easily shifting due to the limiting effect of the installation groove 131, thereby ensuring the safety and reliability of the final electronic product 200.
[0025] Further, please refer to Figure 2The housing 1 includes a body 12 and a mounting bracket 13 disposed within the body 12; the mounting groove 131 is formed on the mounting bracket 13. It is understood that the housing 1 is not integrally formed, as integral forming is difficult and detrimental to production efficiency. Therefore, to ensure production efficiency, in some embodiments, the housing 1 adopts a split structure. Specifically, the housing 1 includes a body 12 and a mounting bracket 13 disposed within the body 12, with the mounting groove 131 formed on the mounting bracket 13. This separate design allows the mounting bracket 13 to be manufactured in the external environment first, and then the mounting groove 131 to be recessed on the mounting bracket 13. The waterproof and breathable membrane 2 is then covered by the mounting groove 131 before being installed into the body. This results in high production efficiency, convenient assembly, and ease of production.
[0026] In addition, please refer to Figure 2 and Figure 3 The cross-sectional area of the section of the ventilated channel 11 near the waterproof and breathable membrane 2 is locally increased to form an expansion channel section 113. Under certain circumstances, water may enter the ventilated channel 11 from the external vent 111. To prevent the ventilated channel 11 of the electronic product 200 from being completely blocked by water and losing its breathability, the cross-sectional area of the section of the ventilated channel 11 near the waterproof and breathable membrane 2 is locally increased to form the expansion channel section 113. With this arrangement, water entering from the external vent 111 will temporarily concentrate in the expansion channel section 113 without affecting the overall breathability of the ventilated channel 11, thus ensuring both waterproofing and breathability of the electronic product 200.
[0027] In addition, please refer to Figure 1 and Figure 2 The housing 1 includes a body 12 and a mounting bracket 13 detachably installed within the body 12. It is understood that in some embodiments, the housing 1 is integrally molded; however, due to the high difficulty of the integral molding process, this results in low productivity. Therefore, in other embodiments, the housing 1 includes the body 12 and the mounting bracket 13 detachably installed within the body 12. This modular production method further accelerates the overall production speed of the electronic product 200.
[0028] Further, please refer to Figure 3The ventilation channel 11 includes a first ventilation channel 11 segment on the body 12 and a second ventilation channel 11 segment on the mounting bracket 13. The external ventilation hole 111 is formed in the first ventilation channel 11 segment, and the internal ventilation hole 112 is formed in the second ventilation channel 11 segment. A sealing gasket 3 is provided between the body 12 and the mounting bracket 13. A sealing communication cavity 31 is formed on the sealing gasket 3 to seal and conduct the first and second ventilation channel 11 segments. The ventilation channel 11 also includes the sealing communication cavity 31. It is understood that, due to the split design, i.e., the housing 1 includes the body 12 and the mounting bracket 13, the ventilation channel 11 also consists of two parts: the first ventilation channel 11 segment on the body 12 and the second ventilation channel 11 segment on the mounting bracket 13. Simultaneously, the external ventilation hole 111 is formed in the first ventilation channel 11 segment, and the internal ventilation hole 112 is formed in the second ventilation channel 11 segment. A sealing gasket 3 is provided between the body 12 and the mounting bracket 13 to seal the gap between them. However, the sealing gasket 3 also has a sealing communication cavity 31 formed thereon to connect the first and second ventilation channel 11 segments. The ventilation channel 11 also includes the sealing communication cavity 31.
[0029] Further, please refer to Figure 1 and Figure 2 The mounting bracket 13 is connected to the body 12 via a threaded connection structure 4; and / or, the mounting bracket 13 is provided with a mounting groove 133 for mounting a power supply device. It is understood that the mounting bracket 13 and the body 12 are connected via the threaded connection structure 4 to form the housing 1, and the mounting bracket 13 is also provided with the mounting groove 133 for mounting the power supply device of the electronic product 200.
[0030] Further, please refer to Figure 1 and Figure 3The threaded connection structure 4 includes a connection hole 41 on the body 12 and a screw 42 passing through the connection hole 41. A sealing ring is fitted on the screw 42, and the sealing ring is at least sealed inside the connection hole 41. It can be understood that the mounting bracket 13 and the body 12 are connected by the threaded connection structure 4 to form the housing 1. Specifically, the threaded connection structure 4 includes the connection hole 41 and the screw 42. The connection hole 41 is located on the body 12, and the screw 42 passes through the connection hole 41 for bolt connection, thereby connecting the body 12 to the mounting bracket 13 to form the housing 1. At the same time, in order to prevent water leakage at the gap of the connection hole 41, the sealing ring is also fitted on the screw 42, and the sealing ring is at least sealed inside the connection hole 41. This arrangement ensures the reliability of the body 12 and the mounting bracket 13 after installation, and also ensures the waterproofness after installation.
[0031] Further, please refer to Figure 2 and Figure 3 The main body 12 includes a shell body 122, with an opening 1221 at one end and a cover 12211 at the opening 1221. An external vent 111 is located at the end of the shell body 122 opposite to the cover 12211. It is understood that the main body 12 includes the shell body 122, with the opening 1221 at one end and the cover 12211 at the opening. The cover 12211 is used to seal the mounting bracket 13 and the interior of the shell 1. Simultaneously, the external vent 111 is located at the end of the shell body 122 opposite to the cover 12211. With this arrangement, during ventilation, such as after opening the cover 12211, air can circulate throughout the entire interior of the shell 1 and then flow out through the external vent 111, thus ensuring the breathability of the electronic product 200.
[0032] This utility model also proposes an electronic product 200, please refer to it. Figure 4 The electronic product 200 includes the waterproof and breathable structure 100. The specific structure of the waterproof and breathable structure 100 is as described in the above embodiments. Since the electronic product 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0033] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
